FAQs

WHEN TO USE Apply Hyaluronic Acid Serum after cleansing, on damp skin. Wait 30-60 seconds, then follow with other treatments.

WHY FIRST AFTER CLEANSING? This serum absorbs best on damp skin and creates a hydration barrier for products that follow. It also soothes skin and balances pH.

SHOULD I HYDRATE BEFORE A TONER? Yes, it helps the toner and other products absorb better by working deep beneath the skin’s surface.

CAN IT BE USED WITH OTHER PRODUCTS? Yes, it works with everything (including actives like Retinol & AHAs) and enhances the effectiveness of other products.

DO I NEED A MOISTURISER? Hydrators (like Hyaluronic Acid) add water to the skin, while moisturizers lock it in. You may need both, depending on your skin type.

WHO IS IT FOR? All skin types, especially dry or dehydrated skin, and mature skin needing a hydration boost.

IS IT AN AHA? No, it hydrates, not exfoliates.

WHAT % OF HYAURONIC ACID IS THERE %? 2% Multi-Molecular Hyaluronic Acid.

WHAT IS THE PH LEVEL? 6.21
